Changes since the third RFC:- Use uninitialized_var() (suggested by Laurent Pinchart);- Fixed a bug in eSDHC SDCLK prescaler calculations because of which we were over-clocking the SDCLK, and that caused CRC errors using some SD cards;- Not a change, but some status: SDHS (50 MHz) cards were tested to NOT work (at least on MPC837x boards) -- this is to be investigated further. SDHC (> 4 GB) cards were not tested, yet.

Changes since the second RFC:- Addressed all comments that were raised by Pierre Ossman. There were too many to mention them all, so here is the link:http://lkml.org/lkml/2009/2/6/320

Changes since the first RFC:- Use of_iomap() in sdhci-of.c (suggested by Arnd Bergmann). Also added Arnd's Acked-by: line for the sdhci-of patch.- Kconfig help text improved (thanks to Matt Sealey and M. Warner Losh).- In "sdhci: Add quirk to suppress PIO interrupts during DMA transfers" patch: sdhci_init() now clears SDHCI_PIO_DISABLED flag, otherwise we won't disable PIO interrupts after suspend.- New patch: "sdhci: Add type checking for IO memory accessors"
